I think you're coming along nicely, Ulrich...just need a waist belt and maybe some leather string to tie the blousy sleeves a little closer to your arm, especially at the wrists and elbows...take it from me, the former Bingo Wing King. lol
I agree with Sir William.
Nothing will get you used to the weight and movement of the armor like wearing it. I wear both my brig and peascod during the "off season" just keep accustomed to the weight and how them move/feel on me. Having everything properly adjusted and the weight better distributed will greatly improve your armor experience.
Same goes for me when I get my Kit together.
